RCC_FLAG_PORRST not detected on STM32U575

Hi, I'm triying to adjust an old code (for STML152) for using it in a new board (STM32U575). The new one can't detect the RCC_FLAG_PORRST, so I wish if someone can tell me the equivalent or how could I read this flag on STM32U575. 

Thanks.

The Reference Manual would be the place to look for that.

Find it on the Product Page for the particular STM32U575 you have; eg,

https://www.st.com/en/microcontrollers-microprocessors/stm32u575ci.html#documentation 

A complex system that works is invariably found to have evolved from a simple system that worked.A complex system designed from scratch never works and cannot be patched up to make it work.
